Online slot machines with bonus feature

This category includes the list with all of the online slots that have a bonus feature. The high popularity of the bonus slots is partially caused by the fact that they propose the players an extra way to win but the spins we are all used to. The video slots games make the main part of the games from this category. There are some 3-reel slots with the bonus feature as well.

The bonus features can be of many different styles too. The pick a box or the free spins are the most common among them. Still, there are the Wheel of Fortune style feature, multi-spin slots (games that have a lot in common with the multi-hand video poker) and games with cascading wins. Any of the listed games offers the players more opportunities to win.

Information on the bonus slots 

You will not find exact details on the appearance of the 1st slot games with bonus in the casinos, but most likely it was in the nineteen eighties. And it does not really matter. Because all we need to know is that they gained so much popularity, that they have become the most loved slot machine style in the online and the offline casinos. The players who join this type of game for first time are almost guaranteed to get some sort of bonus!

The online casinos needed several years to catch up with offline-casinos in terms of bonus slots. Year 2003 was marked with a great breakthrough, as it was the year when the leading gaming software developers started releasing numerous games that had bonus features. And nowadays we can choose from lots of games with multiple types of bonuses.

If we talk about the types of bonus games we can point out several main categories. They are:

Wheel of fortune

It was IGT who made this bonus popular and awards the players with a spinning prize wheel.
 
Free spins slots

The players who use this option get free games with increased win multipliers (as a rule).

Accumulator bonus

Thanks to it the players can collect items to activate some other bonus type or to win prizes.

Multi-Spin bonus 

It’s a game almost similar the multi-hand video poker, but with multiple sets of reels.

Pick a Box bonus

This is a 2nd screen bonus, playing which you can pick items and reveal prizes. 
 
Do not be surprised if you see a game that has for example a pick a box bonus and free spins at the same time, because it is normal for some slot machines to include many types of bonus features. But the games become more and more advanced and it is now not unusual to see even the games that have multiple types of the same feature. For instance the highly popular Thunderstruck II includes 4 types of free spins!
